Now, simply plug in your player and manually install the tcc driver. Tell the driver wizard where the inf file is, and it should do the rest.

You should now be able to use tcctool to boot firmware files.

Obtaining Insignia Firmware The Easy Way

The firmware flash procedure for the NS-DVxG consists of copying a firmware file (*.rom) to the root directory of the device, then disconnecting it from USB. Once this is done, I assume the current firmware verifies the checksum and copies the new firmware to the protected area of Flash memory before deleting the file. Insignia supplies firmware updater and downgrader installers which copy the ROM file to the device. This means if the device is in mass storage mode (plug in the device while it is turned off and the hold switch is on) an end user can can copy the file before unplugging the device and store it for later use.
